Torque can be generated through gearing. I imagine this would work quite
well.
I have some significant experience with both steppers and DC servo motors
(though
not in this application) and either would work fine. Servos are harder to
work with.
The control software is interesting and the external circuitry (amplifiers)
required are expensive
and/or non-trivial to build.
